CIRCULAR LOOM.

SPECIFICATION forming part of Letters Patent No. 522,742, dated July 10,1894. Application led July 19, 1893. Serial No.48 O,896. (Nomodelll Be it known that I, OTTO SCHULER, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Circular Looms, of which the following is a specification.

This invention relates to improvements in looms for Weaving circular or cylindrical bodies, such as lamp wicks, bags, dac.; and the object of my invention is to provide a new and improved loom of this kind which is simple in construction, operates rapidly and is not apt to get out of order.

In the accompanying drawings, Figure lis a plan-view of my improved circular loom,

.y parts being shown in horizontal section. Fig.

2 is a side-view of the same, parts being shown in vertical section. Fig. 3 is a vertical transverse sectional View of the loom, on the line 3 3, of Fig. 2. Fig. 4t is a side-view of the loom, parts being in section. Fig. 5=is a planview of the shuttle. Fig. 6 is a vertical longitudinal sectional View of the same, on the line 6 6, of Fig. 5. Fig. 7 is a vertical trans-` verse sectional View of the same, on the line 7 7, of Fig. 6, and Fig. 8 is an enlarged detail view of the fabric made by the loom.

Similar letters of reference indicate corre sponding parts.

The loom is constructed with a cylindrical base-plate A supporting standards A', on the upper ends of which a ring A2 is fastened, which ring is provided with brackets A3r projecting from its outer edge andsupporting the ring B provided in its upper edges-With a series of notches b for guiding the several warp threads, said `notches being arranged equidistant from each other.

From the ring A.2 a series of radial arms C project inward and support a central disk C for a purpose that will be set forth hereinafter. On two pairs of such arms an inverted V-shaped frame D is erected, in the top of which the fabric roller D is j ournaled, over which the completed fabric passes, a presser roller D2 resting loosely on the fabric on the roller D', which presser rollerl)2 is supported in arms D3 hinged to one of the rods d of the frame D.

y The fabric roller D' is xedon a shaft D4, on one end of which is fixed a cogwheel d that engages a oog-wheel cl2 on a shaft d3 in the frame D, which shaft d3 also carries a ratchet-wheel d4.

i Two levers EE are mounted to rock on the shaft cl3 and are provided at their pivoted ends with rectangular projecting arms, of which one carries at its end the spring-actuated presser-pawl e and the other the springpressed hook-pawl c', which pawls c e engage the ratchet-Wheel d, so that as the levers E E swing said ratchet-wheel is rotated in the direction of its arrow, Fig. Il, by the pawls, and by means of the cog-wheel d2 and CZ rotates the fabric roller D in the direction of its arrow Fig. 3. The lower end of the levers E E carry the rollers e2 and e3, upon which the two cams F F act. The cams F, F', are fixed on the main driving-shaft F2 provided with a suitable erank-handle F3, or, if desired, with a pulleyfor operating the machine by power.

Helical springsA f are connected with the levers E E and the frame of the machine and `drawsaid levers E E( towardkthe adjustable stop-,screws f' f', `by, means of which` the throw of said levers can beadj usted and thus Vthe amount `of fabric rolled or drawn up for each rotation of the shaft F3 be controlled.

From 'the rods d of the frames D arms G project downward and at their lower ends support a guide-ring AG2 forthe circular or cylindrical fabric. According to the diameter of this fabric the ring G2 canbe replaced by a larger or smaller ring. y

The shaft F2 carries at its inner end a beveled cog-wheel H that engages the bevel cogwheel H on the lower end of a vertical shaft H2 suitably journaled in the disk C and in a neck of the bottom plate A of the machine, which shaft H2 carries a large horizontal cogwheel H3 that engages a series of pinions H4 on the lower ends of vertical shafts I guided in sleeves 1 on the inner ends of the'arms C, which shafts I are provided at their upper `ends with pinions I2 rotating in a horizontal These` plane, andserve to shift the shuttles. are constructed as shown in Figs. 5, 6 and 7 and consist of a segmental plate J provided with two anges J projecting from the top and two flanges J2 from the bottom surfacea short distance inward from the curved edges.

The outer or convex edge of the shuttle is provided with a curved rack J 3 adapted to en-V gage the teeth of the pinions l2. The plate forming the shuttle is provided with a recess K, at the ends of which bearings are formed for the spindle of the bobbin or spool K', which is held in place by a latch K2 pivoted on the shuttle-plate J. A tension spring K3 is fastened to one of the webs or ribs J and bears against the spool or shuttle. The thread a passes from the spool or bobbin under the outer flange J then through the slot j of said outer web, then back over thespool and downward and through apertures in the inner web or flange J', as shown in Figs. 5 and 7.

The side edges of the shuttle plates run in tracks formed in the edges of the arms O, and in the outer edge of the central plate O', and the shuttles are also held in place by clips le. As the pinions I2 rotate they move the shuttles around the central plate C on a circular line, a uniform space or opening remaining between the adjacent ends of each two shuttles.

The vertical shaft H2 carries two disks L L, between which a cam-track L is formed, and in said cam-track the rollers M run, that are mounted on the ends of levers M pivoted on standards M2 of the base-plate. The outer ends of said levers-MA are connected by links N with the inner ends of thread-guiding or heddle levers O pivoted to the clips P fastened to the ring A2.

The heddle levers O O are arranged in pairs, one set of levers O being pivoted to the clips Pat the outer ends of the levers and the other set O being pivoted to the clips a short distance from the outer ends, the links N being pivoted to the outer ends of those levers O that are pivoted to the clips a short distance from said outer ends, and the said links N being pivoted to the heddle levers O that are pivoted at their outer ends a short distance from said outer ends, as is clearly shown in Fig. 3.

I have shown four groups of two heddle levers O O each, between each two arms C; but it is evident that more or less may be arranged as circumstances may require, and for each two groups of pairs of heddle levers I have provided a shuttle.

The cam-track L must have as many olfsets as there are groups of pairs of heddle levers, for a reason that will be hereinafter stated.

The warpthreads m pass from suitable rolls or spools through the guide notches b in the top edge of the ring B and then through the eyes o in the free ends of the heddle levers O O and from there to that part of the fabric just completed, that is, at the bottom edge of the ring G2.

I have shown but one thread passing through the eye of each heddle lever, but it is evident that two or more threads may be passed through the eye of each heddle lever without requiring any change in the construction of the machine.

The operation is as follows :--The main driving-shaft is turned either by means of a crank or power and rotates, by means of the gearing shown and described, the vertical shaft H2, whereby the disks L, between which the cam-track L is formed, are rotated in a horizontal plane and rock the levers M up and down, whereby the several pairs of'heddle levers ,0 O are rocked up and down alternately, soas to'form the necessary crosses for weaving. At the same time the cogwheel H3 is rotated, as the same is fixedy on the shaft H2, and it rotates the several spindles l, from which, by means of the gearing described, the several shuttles are rotated in a circle around the disk C', whereby the shuttles are passed through the sheds formed by the warp-threads on account of the up and down movement of the several heddle levers. terweaving of the threads on the shuttles with the warp-threads and the fabric is drawn up as woven by the feed-roller D', which is rotated by means of the ratchet-wheel d4 and the pawls e e' that are operated from the cams F F2 and the levers E E', as shown.

As stated, any number of groups of heddle levers can be arranged according to the nature of the fabric, and a corresponding number of offsets in the track L must be arranged, so that the warp-threads make a new cross every time a shuttle has passed them.

The nature of the weaving is clearly shown in Fig. 8, in which the heavy vertical lines represent the warp-threads and the lighter horizontal lines and partly inclined lines represent the shoot taken fromthe shuttles.

Accordingly as lamp wicks of different sizes or bags of different diameters have to be woven the ring G2 must be replaced by another, as far as the size of the machine will permit.

As shown in Fig. 3, a toothed circular guide Y and Y may be provided for the warp threads.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-e The combination with a ring, of a series of heddle levers O pivoted t0 the same at the ends of said levers, as many levers O as there are levers O pivoted to said ring a short distance from the ends of said heddle levers O', the heddle levers O being pivoted at their ends to the heddle levers 0 a short distance from the ends of said heddle levers O', connectingrods N pivoted to the heddle levers at the point where they are pivoted to each other, pivoted levers M connected with the levers N, a cam-track acting on the levers M, a vertical shaft arranged at the center of the The fabric is thus formed by the in- IOO IIO
